    Abstract Changes to biodiversity from urbanization are occurring worldwide, and baseline data is vital to document the magnitude and direction of these alterations. We set out to document the biodiversity of an urban lake in Eastern Iowa that was devoid of baseline data prior to a renovation project that will convert the site into a major area for human recreation. Throughout the course of one year, we studied the biodiversity at Cedar Lake utilizing the citizen-science application iNaturalist coupled with semi-structured BioBlitz events, which we compared to previous opportunistic observations at the site. From a semi-structured approach to document biodiversity with citizen science, our analyses revealed more diverse community metrics over a shorter period compared to more than a decade of prior observations.

    Abstract The reproductive diversity of extant cartilaginous fishes (class Chondrichthyes) is extraordinarily broad, reflecting more than 400 million years of evolutionary history. Among their many notable reproductive specialisations are viviparity (live-bearing reproduction) and matrotrophy (maternal provision of nutrients during gestation). However, attempts to understand the evolution of these traits have yielded highly discrepant conclusions. Here, we compile and analyse the current knowledge on the evolution of reproductive diversity in Chondrichthyes with particular foci on the frequency, phylogenetic distribution, and directionality of evolutionary changes in their modes of reproduction. To characterise the evolutionary transformations, we amassed the largest empirical data set of reproductive parameters to date covering nearly 800 extant species and analysed it via a comprehensive molecular-based phylogeny. Our phylogenetic reconstructions indicated that the ancestral pattern for Chondrichthyes is 'short single oviparity' (as found in extant holocephalans) in which females lay successive clutches (broods) of one or two eggs. Viviparity has originated at least 12 times, with 10 origins among sharks, one in batoids, and (based on published evidence) another potential origin in a fossil holocephalan. Substantial matrotrophy has evolved at least six times, including one origin of placentotrophy, three separate origins of oophagy (egg ingestion), and two origins of histotrophy (uptake of uterine secretions). In two clades, placentation was replaced by histotrophy. Unlike past reconstructions, our analysis reveals no evidence that viviparity has ever reverted to oviparity in this group. Both viviparity and matrotrophy have arisen by a variety of evolutionary sequences. In addition, the ancestral pattern of oviparity has given rise to three distinct egg-laying patterns that increased clutch (brood) size and/or involved deposition of eggs at advanced stages of development. Geologically, the ancestral oviparous pattern arose in the Paleozoic. Most origins of viviparity and matrotrophy date to the Mesozoic, while a few that are represented at low taxonomic levels are of Cenozoic origin. Coupled with other recent work, this review points the way towards an emerging consensus on reproductive evolution in chondrichthyans while offering a basis for future functional and evolutionary analyses. This review also contributes to conservation efforts by highlighting taxa whose reproductive specialisations reflect distinctive evolutionary trajectories and that deserve special protection and further investigation.

    Abstract Abstract: Disconnected duct syndrome (DDS) is an adverse sequela of acute necrotizing pancreatitis in which there is disruption of the pancreatic duct leading to a failure to deliver pancreatic secretions into the duodenum. Its presentation may range from a persistent external pancreatic fistula to a treatment-resistant pancreatic pseudocyst. The diagnosis is often delayed in the acute setting if there is concurrent necrosis as management is often directed to the associated peripancreatic fluid collection. A combination of imaging modalities may be required to evaluate ductal anatomy. No definitive consensus has been achieved regarding the optimal treatment strategy for DDS, and there is a lack of published level I evidence on the topic. Treatment should be tailored to each individual patient, depending on the anatomy of ductal disruption, the presence of sepsis, the degree of physiological derangement, and the patients' performance status. Patients with DDS represent a specific cohort of patients with complex pancreatic disease that requires the input from a diverse multidisciplinary team to ensure that a good clinical outcome can be achieved.

    Abstract Background: The role of a very low-calorie diet (VLCD) before cholecystectomy in obese patients is unclear. This study evaluated whether VLCD could be used as a risk mitigation strategy for this high-risk patient cohort.
    Patients and methods: A systematic review and meta-analysis was performed (PROSPERO ID CRD42022374610). The primary outcome was to determine the impact of pre-operative VLCD on the operative findings and ease of dissection during laparoscopic cholecystectomy (LC).
    Results: Two studies were included with a total of 84 patients. VLCD was associated with a significantly easier Calot's dissection (MD: -0.58 (95% confidence interval [CI] [ -1.03, -0.13], P = 0.01) and was associated with a significantly higher rate of pre-operative weight loss (MD; 2.92 (95% CI [2.23, 3.62], P = 0.00001).
    Conclusions: The published evidence regarding VLCD before cholecystectomy in obese patients is limited. After acknowledging the limitations of the data, VLCD is associated with a significantly higher rate of weight loss preoperatively and directly impacts the ease of intraoperative dissection of Calot's triangle. Routine use of VLCD should be considered for all obese patients undergoing elective LC.

    Abstract Background: People with diagnoses of intellectual disability or serious mental illness have higher mortality rates due to physical comorbidities; better understanding is needed to guide best practice in provision of palliative care for these populations.
    Aims: To identify multivoiced perspectives, drawn from lived experience of: what works, and what does not, in palliative care for people with intellectual disability or serious mental illness; challenges in, and opportunities to improve, palliative care.
    Design: A systematically constructed qualitative meta-ethnography. Protocol published (PROSPERO: CRD42021236616).
    Data sources: MEDLINE, PsychINFO, CINAHL PLUS and Embase used without date limitations. Papers published in English, containing qualitative data on palliative care provision for people with a diagnosis of intellectual disability or serious mental illness were included. Global five-point strength score applied for relevance/quality appraisal.
    Results: Familiarity (of location, people and/or things) is important for good palliative care. Assumptions and misunderstandings about the role of mental capacity assessment to appropriately involve the patient in decision-making are common. Adapting training for palliative care staff to address concerns and beliefs about mental illness is one of the methods that helps avoid diagnostic overshadowing. Proactive identification of service arrangements to meet needs of persons with personality, psychotic, delusional and bipolar affective disorders will help optimise care.
    Conclusions: Evidence, including the voices of people with intellectual disability or serious mental illness is urgently needed to guide efforts to improve their access to and experience of palliative care. More evidence is especially needed to understand, develop and implement best practice for people with psychosis, bipolar affective disorder, mania and personality disorder.

    Abstract Background: Postoperative pancreatic fistula serves as the principle cause for the morbidity and mortality observed after pancreatectomy. Continuous drain irrigation as a treatment strategy for infected pancreatic necrosis has previously been described; however, its role adter pancreatectomy has yet to be determined. The aim of this study was to determine whether continuous drain irrigation reduces postoperative pancreatic fistula.
    Methods: A meta-analysis of the pre-existing literature was performed. The primary end point was whether continuous drain irrigation reduced postoperative pancreatic fistula after pancreatectomy. The secondary end point evaluated its impact on postoperative morbidity, mortality, and length of stay.
    Results: Nine articles involving 782 patients were included. Continuous drain irrigation use was associated with a statistically significant reduction in postoperative pancreatic fistula rates (odds ratio [95% confidence interval] 0.40 [0.19-0.82], P = .01). Upon subgroup analysis, a significant reduction in clinically relevant postoperative pancreatic fistula was also noted (odds ratio 0.37 [0.20-0.66], P = .0008). A reduction in postoperative complications was also observed-delayed gastric emptying (0.45 [0.24-0.84], P = .01) and the need for re-operation (0.33 [0.11-0.96], P = .04). This reduction in postoperative complications translated into a reduced length of stay (mean difference -2.62 [-4.97 to -0.26], P = .03).
    Conclusion: Continuous drain irrigation after pancreatectomy is a novel treatment strategy with a limited body of published evidence. After acknowledging the limitations of the data, initial analysis would suggest that it may serve as an effective risk mitigation strategy against postoperative pancreatic fistula. Further research in a prospective context utilizing patient risk stratification for fistula development is, however, required to define its role within clinical practice.

    Abstract Attachment theory and the science of emotion provide a strong foundation for intervention at the family system level. Four therapeutic models in particular, Attachment-Based Family Therapy, Emotion-Focused Family Therapy, Dyadic Developmental Psychotherapy, and Emotionally Focused Family Therapy, demonstrate how a broad and accurate view of attachment relationships and emotion can be utilized to effectively intervene for a variety of presenting problems in a relational and empathic way for all involved. This paper continues a conversation that began at the Summit for Attachment and Emotion in Family Therapy in 2021 and aims to foster openness, collaboration, and affirmation between four different models of family therapy with shared theoretical roots. The presenters at the Summit and the authors of this paper view similarities across these models as validating and differences as opportunities to serve more families in unique ways, learning from one another's creativity to promote healing within families in the most effective and efficient ways possible. The paper frames the value of attachment theory and emotion science for family therapy, discusses the importance of learning from a variety of models with shared theoretical roots, presents brief summaries of the four models presented at the Summit, compares the models for similarities and complementarities, and shares highlights from each of the presenters from the Summit.
